i just put a new version that has one fix -- basically if you are decreasing the speed it changes the speed before changing the voltage.
it should help with crashing, but i accidentally coded it backwards and it didn't crash for me like that either. The crashing could also have been a timing issue which i've fixed by complicating things, so YMMV.

So are you suggesting me to change my settings? how about the guy whos running it at 1,35Ghz?

Mine is running at 1350mhz for +12 hours , no lag/freeze/reboot so far , everything works fine .

I don't think the chip would get damaged at these frequencies , my N900 runs at 1ghz for almost a year and nothing has changed . That is +400mhz on a 600mhz chip , I don't think +350 on a 1000mhz chip could damage anything since they are such similar .

I changed them a bit since I got voltage control working , the new description is this :

1Ghz - 1000mhz , no more smartreflex involved because I always get instant reboot when I press on 1Ghz icon .
1.2Ghz - 1200mhz , no SR , up threshold set to 75 and default voltage
1.3Ghz - 1300Mhz , no SR , up threshold set to 75 and 1387500 voltage
EnableSR - as title says
DisableSR - ........... potato
